Specification of Letters Patent.

Patented Dec. 29, 1914.

Application filed November 21, 1912. Serial No. 732,648.

To all 107mm it may concern Be it known that I, ERIK Gns'rar DAN- BERG, of the village of Big River, in the Province of Saskatchewan, Canada, have invented certain new and useful Improvements in Combination Chairs and Beds, of which the following is the specification.

My invention relates to an improvement in combination chairs and beds and the object of the invention is to provide a chair which can be readily converted into a couch or bed.

It consists essentially in a chair having the sides thereof formed from a number of pivotally connected bars arranged'so that they can be extended, cross beams pivotally secured to the aforesaid bars, extending members secured to the beams, a back piece and foot piece, hinges connecting the foot piece with one of the beams and cables secured to the foot piece and one of the beams, the parts being arranged and constructed as hereinafter more particularly described.

Figure 1 represents a side view of the device as it appears when used as a chair. Fig. 2 represents a vertical sectional view centrally through the same. Fig. 3 represents a side view of the device when extended and used as a bed. Fig. 1 is a plan view of the parts as they appear in Fig. 3. Fig. 5 represents an enlarged detailed perspective view showing the manner of bracing parts of the device. Fig. 6 is an enlarged detailed vertical sectional view through the arm of the chair, the section being taken in the plane denoted by the line X X Fig. l and looking in the direction indicated by the arrow. Fig. 7 is an enlarged detailed vertical sectional view through one of the beams, the section being taken through the intersecting points between the rear leg forming bars.

In the drawings like characters of reference indicate corresponding parts in each figure.

1, 2, 3, 4:, 5, 6, 7, and 8 represent palrs of bars pivotally secured one to the other by top bolts or rivets 9 and bottom bolts or rivets 10. The bars 5 form the support for the back of the chair and are necessarily longer than the other bars. They are connected at the top by a cross rod 11 which not only reinforces them but receives the canvas or such like flexible strip 12 forming the chair back.

The bars at each side are connected centrally by cross rods 13 which support cross beams 14-, 15, 16 and 17, these bars forming in reality the support for the seat of the chair and also support for the bottom of the bed when the device is extended this being better understood as the description proceeds.

18 are cross braces passing between the lower ends of the bars 1, 2, 3 and a and 19 are angle braces reinforcing the cross braces.

The canvas 12 is stretched over the cross rod 11 and has the ends thereof bound together and securely fastened such as by tacks to the under side of the cross beam 14.

20 is a foot piece secured by hinges 21 to the upper ends of the bars 4- which it will be noticed terminate at the ends of the beam 17. The foot piece is simply a rectangular frame presenting cross rods 22 around which I have placed a strip of canvas 9,3.

241 and 2-5 are two cords or cables permanently fastened at one end to the lower end of the foot rest and at their other ends to the cross beam 14:. The cords are supported by eyes or staples 26 carried by the beams 15 and 16. It is to be noticed that the cables or cords pass over the beam 17. The beams 14:, 16 and 17 carry sets of slots or members 27, 28 and 29 respectively, the member 28 being considerably shorter than the member 29 while the members 27 are considerably longer than either of the other two members.

When the device is being used as a chair the members 27 are directed upwardly and form a rest for the back, the upper tips of the members in this position bearing against the cross rod 11. The members 27 are resting on the beams 14 and 15 while the members 29 are resting on the tops of the members 28.

It is here to be noticed that two of the members 28 are provided with openings 28 which receive pins 30 projecting from the face of the beam 14: when the members 27 are elevated as indicated in Figs. 1 and 2. This construction serves to anchor the members 28 to the beam and prevent the chair from collapsing.

Arms 31 are secured to the side bars 5 by pivot pins 32 and have their under faces grooved out at 33 to receive the upper ends of the bars 1, 2, 3, 6, 7 and 8.

Each arm is fitted with a catch or hook 34 designed to engage with eyes 35 and 36 presented by the bars 8 and 6 respectively.

These arms and hooks give rigidity to the 'a bed he releases the hooks from the eyes 85, raises the arms and extends the side bars. As the side bars extend the cords are tightened with the result that the foot piece 20 is swung up to the position shown in Figs. 3 and at of the drawings. As soon .as the foot piece reaches the upper position and is held there by the pressure of the persons feet lying upon the bed, so that one can not extend the device farther as the cords are then drawn tight. In the extended position the members 27 are thrown down and rest on the beam 15.

A mattress can be placed on the members inthe extended position of the chair.

The hooks 34- are shown connected up with the eyes 36 in Fig. 3 of the drawings wherein the chair is shown extended.

termediate longitudinal members, said in termediate longitudinal members overlapping the rear longitudinal members when said members are in extended position, said rear longitudinal member being adapted to extend in a vertical direction when said side bars, are in retracted position.

Signed at Big River this 12th day of April, 1912.
